This is my build for this years Amature IASCA and USAC-I competition season!

I am doing a complete overhaul of everything in my toaster doing a true 4 way active system.

I am about 70% done, the front stage is in and all wired up. The deck/RUX are together and ready to be installed. I am still working on the mounting of the Processor and doing a false floor in the hatch for the amp rack and subwoofer .

cool start. i like the speaker baffles. you may want to seal up the dash speakers, the gaps around may likely cause phase interference. the H701 is so flexible, you'll enjoy tweaking each driver separately.

Thanks!

Going to seal them up with some acoustic foam, it is a pretty tight fit between the baffle and stock grill. I am open to other suggestion though!

Looks very nice so far. I'd imagine that car is a bit of a dream for imaging, just being so symmetrical. Any plans on spheres for the tweets?
And I got a little sexually excited at the site of that Red Hook Extra Strong Bitter.
The Alpines look gorgeous!
Curious why you went with Fat Mat though? I've heard a bit of mediocre reviews from them?
Also, the techflex is gorgeous :)

closed cell foam is ok. modeling clay is another good solution.

Fatmat was priced right and I have never had any issues with it. It has been used in 2 other cars I have had a hand in recently and never had any issues other then cut fingers!

As for the tweeters I might recess them into the pillar and hide them but for now they are as you see, I will be cleaning up the install on them as soon.

Fair enough. I suppose as long as you have used it before with no problems, why not continue!
So no plans for spheres/pods for the tweets? Just curious cus I've heard people raving about them for SQ oriented set-ups haha. They certainly do look nice in the pillars now though.

great install so far. I bet this will sound very good when you are done. I agree, anything you do to get your tweeters more on axis is only going to help how it sounds.

Thanks for the compliments!

About the tweeters, Mine are going to be dialed way down (power wise) and running upwards of 8-10k for ambient fill. My 3's will be doing the majority of the work and I was told from a Hybrid TM that if I really wanted to I could just run the 3 and 6.5 with no tweet.

I am trying to keep the car stock looking inside as possible. I do like the Orb Idea but since this is my daily driver and with huge balls on my pillars would scream OH A SYSTEM IN HERE, When I am done the pillars/tweeters will be pretty stealth.

My tweeters were originally in the dash and I had amazing depth and image and I scored really high on those. If it ***** and I can always change it later! :)

Only update was putting modeling clay (Thanks Keep_Hope_Alive for the idea) around the gap's of the baffle to try and minimize airflow around the speaker. There is not really anything I can do about the 5 holes for the grille mount. I am going to get some black felt fabric and cover the baffles to clean them up some.

I will be doing some more updates over the week and a lot of work this weekend!

Shoulda got AT bruh bruh. I was thinking that having those 3inch drivers bouncing off the dash like that could cause issues on the higher fequencies, also curious as to how they will play out with the tweeters there

You mean bouncing off the windshield? I had my 1" mounted there and I had no issues, also the stock 3" were mounted there as well. The stock system in these xB's were not all that bad out of the box.

I will hopefully get to power it up this weekend........ I hope.

You gonna run some oldschool kicker ss? I had my tweets like that and I was given hell at the meca comp for it

No Kicker (Although I do have a pair of 3" Resolutions) I am running a full Hybrid Audio driver system including the sub, We shall see about the tweeters, we have a Honda Civic with the Imagine tweeters set up just like mine in the pillars and so far no problems, the Civic has some of the best width and depth and image I have heard in a car without the use of TA. Just a few hours of tuning and tweaking have gone into it as of right now and it has scored pretty high in rookie.

You should hear my Fit. Its still a work in progress but I dont use any TA and it is by far the best as far as stock locations go. I was more or less joking about geoffs amp ahah

lulz, did he get that amp from his mom yet?

Keep me posted on if it works!

:Update:

Although the photos do not show a lot of "progress" making this enclosure has taken quite a bit of time and it is pretty close to being finished.

This is my first time working with fiberglass, a good friend of mine has taken the time to show me the basics of this process and to be honest I have no idea why I was so worried about working with fiberglass. For the most part it is a pretty simple process that takes a lot of time!

What you see going on here is the stock Scion xB foam storage bin being wrapped with fleece and used to make a mold for the base of the sub woofer enclosure.

This took about a gallon of resin so far and I still have quite a bit of coating to do to get it solidified enough to support the pressure of the i10SW.

Anyway here are a few photos to gawk at. I will be applying a coat of resin every day on the outside and inside of the enclosure.

Small but big update, its also been a minute since I have posted here in this thread, no photos yet but the front stage is in and up and running. Got it all dialed in and put it on the RTA and smoothed it out. All i have to say it wow, softball sized center stage, width and depth are out past the a-pillars and on the hood. No solitified sub yet since the false floor is taking more time then I thought it was going to.

I Got to double check these numbers but i believe this is what i have the x-overs at.
8" Sub 40-1hz 30db 20hz +6
6.5's are 40-100 24db
l3's are 100-8k (12db)
1" are 8k-^ (12db)

So for my first show with this being tossed together for points for a x2 show this last weekend I got a pretty good score 217.

But I have to say that a 217 for maybe 3 hours of tuning and 1 hour doing RTA work that I got a very respectible score.

I went a head and put in my DD1508 that I use for testing amplifiers it is in a 1cf vented enclosure tuned to 35hz. I had it crossed off at 40hz with a 30db slope with 20hz +6.

As far as the L3 xover points this was suggested by Bill Pleasent of Team Hybrids who is my neighbor and has lent his hands and ears to this build. The L3's really sing nice and blend well with the I6.5's. I am thinking I might ditch the tweeters and try to run just the L3's. I wish I would have taken a photo of the RTA graph it was pretty impressive.

These Gen1 xB's have amazing acoustics for a good front stage with great depth and image with that windshield angle being as steep as it is.

Anyway here is my score sheet. I cannot wait to get the back done and get a good week or more of hard core tuning and RTA work in.
